When tiling directly over Wet-seal™ Enviro-coat Membranes, polymer modified, flexible cement-based tile adhesives are recommended.  Wet-seal Enviro-coat Membranes have been independently tested and are compatible with quality C2S1 and C2S2 tile adhesives. Ensure that the tile glue is water based. Solvent based adhesives are not compatible with Wet-seal™ Enviro-coat Membranes.  Premixed (Dispersion) tile adhesives are not recommended.  All tiling is to be carried out to AS 3958.1- 2007 “A Guide to The Installation of Ceramic Tiles”.
